\ Letters Patent No. 91,193, dated June 8, 1869.

IMPROVEMENT IN ELEVATORS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom 'it may concern Be it known that I, JA'MES' Yos'r, of White Deer township, in the county of Union, and State of Pennsylvania, have invented a new and useful Improvement in Elevators; and I do hereby declare the following to be a full, clear, and exact description ofthe same, sufiicient to enable others skilled in the art to make and use the same, reference being -had to the accompanying drawing, forming part of this specification, in which- Figure l is a front elevation of abarn containing my elevator. l

Figure 2, a' top view of the same, the roof-framing being removed.

Figures 3 and 4, detail views to be hereinafter referred to.

My improvements relate principally to that class of .elevators employed for raising hay and grain, and storing the same in barns;

The object of my invention is to improve the construction of the elevator patented to H. Keck, dated June 23d, 1868, so as to render. the same capable of easier and more economical operation, and wider application. V

These improvements consist in soarranging the hoisting-ropes, that the same may be wound up by a man or horseftravelling in a circuit within the barn; in constructing the shafts from which the elevator-platform is suspended in sections, jointed together in such a manner as to be detachable, onefrom another, and adapted to be removed from one position to another' in the barn, for storing grain and hay at different points; in constructing the dumper without teeth, whereby clogging is prevented, and with strengthening-braces, and operating the same by simply drawing on a cord; in so constructing the drums overwhich the draughtropes pass that they may be detached from one scction of the sectional shaft, and applied at another point; and in the applicationand mode of operating pawls for retaining the elevator-platform at any point, as will be hereafter fully described.

My invention will be fully understood by reference to the accompanying drawings, considered in connection with the following detail description.

Similar letters of reference indicate like parts rin the several figures.

In the drawings- A may represent the barnvfloor.

B B, uprights;

C, the horizontal plate;-

D, the ridge-pole; and

E E, rafters.

Mounted in bearings, a, aiiixed to horizontal crossbars F, are shafts, G G, G G.

One series of shafts, those markedG G, for instance, has square ends, b b, which t in sockets of corresponding shape in the adjacent ends vof the sections G G.

From the shafts G G, or G G', the elevating-platform or carrier, H, is 'suspended by ropes,.ec, so attached to the shafts as to be wound thereon by the rotation of the latter.

On the sections -of the shaft are tted drums, I I, which, as seen in iig. 3, are made with square eyes, -so as to turn with the shaft, and still be readily removable therefrom, being held by no other means.

To the periphery of each drum is fastened one end of a draught-rope, d d. l

These ropes pass under and around a central pulley, e, and are then made fast at one point to the periphery ofa drum, J, fitted on a vertical shaft, K.

This shaft may have its bearings in the door of the barn, and in a removable beam, L, above, or it can be set in any suitable bearings outside of the barn, or inv any other part of the same, as occasion requires.

In the shaft K is fitted a horizontal lever, M, which mav be turned by a man or horse travelling in acircle.

The dumper (fig. 4) is constructed of a straight piece, f, with T-head, g, and crossed braces, h h.

The dumper is hung by a pivot to the ridge-pole, and is operated by means of a rope, fi, attached to it; thence passing over pulleys, j j, and extending down, within reach of a person upon the floor of the. barn.

In one face of each drum is set a concentric series of pins, it k, with which pawls N N engage.

These pawls are pivoted at their inner ends to a horizontal transverse beam in the barn.

To each pawl is attached one end of a cord, m. These cords areunited, and extend down, so as to be in reach of a person on the barn floor.

The operation is as follows:

The wagon on which the hay or grain is transported from the iield to the barn, is driven in under the shafts from which the ropes depend. These ropes are now made fast to hooks on the wagon-body, rack, or bed.

Now, when the shaft K is turned by means of a man or horse at the lever M, the draught-ropes will 'be wound on the drum/J, the shafts G rotated, and the wagon-bed or rack lifted oi the bolsters, and elevated to the desired height, at which it is retained by the pawls N N, falling by gravity, and engaging with the pins lc k, on the drums 1.

By drawing on the cord'ft, the dumper is made to pass over the wagon-bed, from which it dischargesall the hay or grain into its appropriate mow.

The cord m is now drawn upon, thus lifting the pawls N N, and freeing the drums when the wagonbed descends by its own weight, and rests upon the holsters.

The advantages of my improvements will be readily appreciated by all practical farmers and mechanics.

The driver of the hay-wagon can do all the work of storing the load in the barn, unassisted, as the length of the lever M will render it easy to elevate the load, which is retained automatically at the desired elevation, while the driver operates the dumper.

By applying the power within the barn, the work is rendered easier and better in every respect.

The construction of the dumper with the braces, as described, and without teeth, prevents clogging, and gives an eliective bearing against all parts of' the load. 1

By making the shafts in sections, fitting them in detachable bearings, and providing them with removable drums, one or two series of shafts, and a single set of wheels, will be all that is requisite in a large barn, as they can he readily taken from one place to another and applied anywhere.

Having thus described What I claim as new, ters Patent, is-

my invention, and desire to secure by Let- 1. The dumper f g, with crossed braces, h h, all

constructed, arranged, and operated, as herein described.

2. The pawls N N, arranged as described, and operated simultaneously, in combination with the drums I, on the sectional shafts G G', for the purpose set forth.

3. The removable sectional shassG G, G' G', joined together, substantially in the manner described, and provided with the detachable drums I, all constructed, arranged, and operating, substantially as described.

4. The combination and arrangement of the sectional removable shafting, detachable drums, pawls N N, and movable shaft K, with drum J, and lever M, all operating, substantially as herein set forth.

To the above specification of my invention, I have signed my name, this 29th day of April, 1869.

JAMES YOST.
